UNITED STATES PATENT OFFICE- ROLLING RADIATOR SHUTTER.

Application filed March 11, 1925. Serial No. 14,627.

This invention relates to rolling radiator shutters and the like, and particularly to a shutter for use'on automobiles for regulate ing the exposed area of cooling surface and thereby controlling the passage of air through the radiator and automatically regulating the temperature of water therein.

One object of the invention is to providea very simple, substantial and ein'cient attachment of pleasing appearance which can be quickly attached to, or removed from the automobile radiator, and which can be operated from the drivers seat in the vehicle.

Another object is to provide a frame which can be stamped from sheet metal, which will be light in weight, and very economical to manufacture.

With the above and other objects in view, the present invention consists in the combination and arran ement of parts, hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes ma be made in the form, size, pro ortion an minor details of construction, without departing from the spirit, or sacrificing any 0 the advantages of the invention.

In the drawings:

Fig. 1 is a fragmenta side view of an automobile-showing our improved radiator shutter in place thereon.

Fig. 2 is an enlarged fragmentary sectional view of the radiator showing the pipe thegein for the passage of the operating cor Fig. 3 is an enlarged fra enta sectional edge View of the low i end f the shutter proper.

Fig. 4 is a front view of the shutter. Fig. 5 is a sectional plan vlew taken on the line 55 of Fig. 4, the curtain being removed.

Fig.- 6 is an edge view illustrating one method of securing the pull chain in position.

Fig. 7 is a front view of the locking plate. p

In cold climates where the temperature drops below the freezing point at certain seasons of the year, it is necessary to provide means for regulating the area of the exposed radiator surface to prevent the freezing of the cooling mixture, and when the passage of air is partially or completely cut off, .the mixture warms rapidly insuring the engine operating in the proper manner.

Antifreeze solutions are used to prevent freezing but, unless the area of the radiating surface is reduced, the cooling mixture stays very cold, causing the motor to miss and sputter, with ourimproved shutter de vice the exposed radiating surface can be regulated, so that the mixture becomes warm quite quickly, after which the shutter can be lowered if desired.

Referring now to the drawings in which we have shown the preferred embodiment of our invention, the numeral 1 indicates the shutter frame proper, which is usually shaped to conform to the contour of the radiator shell. This frame is provided with a-large central opening'2, the edges 3 of the frame being flanged and turned to provide vertically disposed ways or guides 4 in which the edges of the flexible curtain 5 are adapted to travel and which revent wind getting behind the curtain an blowing and fiapp'ing same.

A conventional spring actuated roller 6 is mounted in the lower end of the frame, suitable openings beingprovided in the side -walls thereof to receive the pintle and gudeon of the roller, said lower end being enlarged to house the roller and curtain, thence gradually narrowing to accommodate and guide the curtain proper.

v A transversely disposed strip 7 is pro- Vided near the lower end of the frame being welded or otherwise secured thereto; the

. extreme ends 8 being slightly bent to eliminate the possibility of catching and tearing the edges of the curtain, the up er edge. of this strip-frictionally engages t e inner surface of the curtain at all times and serves as a drain for melting snow, rain etc., which might lodge, or beblown or 'ven between the curtain and the radiator, the heat of the radiator servingto melt the ice and snow.

The upper ends of the ways or guides are capped y flanging the material thereover to exclude snow, ice and other foreign matter.

A small sheave or pulley 9 is journaled in a bracket 10 riveted or welded to the. top section of this frame, and around which a cord 11 is threaded, one end of the cord being secured to the curtain as shown, thence leading up (close to the vehicle radiator 12,

and over the sheave 9), thence through an opening in the frame and through a small pipe section 13 which extends through the radiator core. A chain 14 is then attached to the end of the cord 11 and leads to the instrument board 15 of the vehicle.

A conventional locking plate 16 is secured to the instrument board and is provided with an open slot 17 so that the chain may be'hooked therein to hold the curtain in any adjusted position, we find that a fabric cord is short lived in this position, and therefore provide a chain as described.

It will of course be obvious that various devices such as reels and'the like may be provided for winding the chain to adjust the shutter if desired, but we find the method described to be practical, convenient and economical. J

The attachment is secured in place by means of small threaded bolts 18 which extend through the radiator core, a nut 19 bediator shutter for regulating the current of.

air passing through the radiator.

What we claim is 1. A rolling radiator shutter for automobiles comprislng a sheet metal frame having an enlarged central opening, the edges of the frame being turned to form guides, the lower ends being curved outwardly and enlarged and having" a roller mounted therein and spaced ahead of the automobile radiator, a flexible curtain wound on the roller at the front side'thereof, the edges of which curtain travel in said guides, and an inclined drain strip secured to the frame adj acent the curved portion and extending upwardly and forwardly over the roller'and frictionally engaging the back of said curtain.

2. The combination with an automobile, of a rolling radiator shutter comprising a sheet metal frame having a central opening, the edges of the frame being turned and bent to form guides, the lower ends being curved outwardly and having a roller mounted therein and spaced ahead of the radiator, a flexible curtain wound on the roller at the front side thereof, the edges of which curtain travel in said guides and the roller being arranged at the rear of the cur-- tain, a drain strip secured to the lower end of the frame and extending u wardly and forwardly over the roller an frictionally engaging the inner surface of the curtain, a sheave journaled to the upper edge of the frame, and an operating cord attached to the curtain and leading around said sheave and to the dash of the automobile for adjusting said curtain.

In testimony whereof we aflix our signatures.
